Andre Johnson anyone?
Last year with the Colts was a disaster, but his last 3 years in Houston before that showed no real signs (at all) of wash up as he had:
1,598 yards
1,407 yards
936 yards in essentially 14 games because he got a concussion right after the 1st quarter of a game and missed that whole game and the next week. Taking his YPG average, it would 1,070 yards over 16.
He got plenty of run and targets with the TEN starting offense this weekend and no reason to believe he can't go back to being a 1,000 yard receiver if Mariota takes the next step (which I think many think he will). Despite 900-1,000 yards not being "fantasy stud" stats, they are super solid for a WR 4-5/bye week fill in who is currently not even being drafted in 98% of drafts (other than those in Houston most likely due to his legend status).
